I am obese. Like, I am comfortable having two seats in the plane type of obese. I'm well aware of that and I really don't like to bother people with my weight. A week ago, I was going to conference by plane and because I was going alone, I brought two seats. I fit in one, but usually my side is touching the person next to me and I feel uncomfortable for them. It happened to me once that they gave me nasty looks and I feel extremely uncomfortable the whole flight. So, I sat down in the plane and put the armrest up so I would really be comfortable. Some couple came and they both sat next to me because they got separate seats and they noticed the seat next to me was empty. Exactly what I was afraid would happen. My side kept touching the guy next to me and he even pushed me a bit when he moved in the seat. I was feeling extremely uncomfortable and asked him if he could go to his seat because I bought this one for my comfort. He told me no since the seat is empty and he wants to be with his girlfriend. Well, I told him I understand, but I feel uncomfortable and I paid for the second seat so exactly this doesn't happen. He refused again and started to chat with his girlfriend. I called the flight attendant and quietly told her what is happening. She asked the guy to leave my seat and he and his girlfriend gave me a nasty look. The girlfriend mumbled something like, fucking fat bitch under her breath, but nothing directly to me. So am I the asshole for insisting on him to leave?
